Ronald Reagan’s daughter in a new op-ed writes that her father would be “appalled” by President Trump‘s presidency.

Patti Davis reflects on her father’s “love for America” in The Washington Post ahead of the anniversary of his death, and what he would think of the nation today.

“He would be appalled and heartbroken at a Congress that refuses to stand up to a president who not only seems ignorant of the Constitution but who also attempts at every turn to dismantle and mock our system of checks and balances,” Davis wrote.

She also said that her father would call on Americans “to recognize that the caustic, destructive language emanating from our current president is sullying the dream that America once was.”
